Yeah, I'm running 1.15 and I applied the patch zip to the mod, so I don't know what's wrong. I'll try the windowed mode thing when I get back from going out to eat.
Nevermind... I ran it in windowed mode and read the error message and it was choking on every single file, so I went and looked at the mod folder more carefully and realized that WinRAR had unpacked the zip into a subfolder. Bad WinRAR, bad.
